I. Background The Network File System (NFS) allows a system to share directories and files with others over a network. By using this, users and programs can access files on remote systems almost as if they were local files. The rpc.rquotad utility is an rpc(3) server which returns quotas for a user of a local file system which is NFS-mounted onto a remote machine. II. Problem Description A change in rpc.rquotad made it send RQUOTA v2 requests instead of RQUOTA v1 requests. Some vendors would send RPC_PROGNOTREGISTERED ("Program Not Registered") response instead of the desired RPC_PROGVERSMISMATCH ("Program Version Mismatch") response, preventing the mechanism from working. III. Impact The quota(8) command will not be able obtain quota information for some NFS server vendors. IV. Workaround No workaround is available. Systems not using quotas on NFS mounted file systems are unaffected. V. Solution Upgrade your system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Perform one of the following: 1) To update your system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install 2) To update your system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch https://security.FreeBSD.org/patches/EN-20:07/quotad.patch # fetch https://security.FreeBSD.org/patches/EN-20:07/quotad.patch.asc # gpg --verify quotad.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile the operating system using buildworld and installworld as described in . Restart the applicable daemons, or reboot the system. VI. Correction details The following list contains the correction revision numbers for each affected branch.

I. Background The ipfw system facility allows filtering, redirecting, and other operations on IP packets travelling through network interfaces. II. Problem Description Incomplete packet data validation may result in accessing out-of-bounds memory (CVE-2019-5614) or may access memory after it has been freed (CVE-2019-15874). III. Impact Access to out of bounds or freed mbuf data can lead to a kernel panic or other unpredictable results. IV. Workaround No workaround is available. Systems not using the ipfw firewall are not vulnerable. V. Solution Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date, and reboot.

I. Background FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured Open Source toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a full-strength general purpose cryptography library. II. Problem Description Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognized signature algorithm is received from the peer. III. Impact A malicious peer could exploit the NULL pointer dereference crash, causing a denial of service attack. IV. Workaround No workaround is available. V. Solution Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Perform one of the following: 1) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install # shutdown -r +10min "Rebooting for a security update" 2) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch https://security.FreeBSD.org/patches/SA-20:11/openssl.patch # fetch https://security.FreeBSD.org/patches/SA-20:11/openssl.patch.asc # gpg --verify openssl.patch.asc b) Apply the patch.
